Eye Vitamins and Foods

Experts say a diet that includes plenty of vegetables and fruits is the best for eye health. It’s easy to forget about how foods can impact your eyesight, but it’s important to be aware of what you eat- especially if you have an ocular condition or sensitivity.

Eye vitamins and foods are important to the health of your eyes.


As you become older, deteriorating eyesight may seem like an inescapable inconvenience, but with the appropriate diet, you may maintain clear vision for far longer than you would imagine. Carrots and leafy green vegetables, for example, are regarded as some of the healthiest foods for your eyes because they include antioxidants and eye vitamins such as vitamins C, E, A, and zinc, as well as carotenoids such as lutein and zeaxanthin. These protect the macula, lens, and cornea of the eye and reduce free radical damage and inflammation, which destroy eye tissue.

The eyes grow more vulnerable to injury as we age due to an unhealthy lifestyle and an overactive immune system, which causes the body to become overwhelmed with defense cells and hormones that destroy sections of the eyes.

How might eye vitamins help you maintain your eyes looking fresh and bright as you get older? A poor diet was revealed to be a substantial risk factor for age-related macular degeneration and cataracts in the Age-Related Eye Disease Study, a clinical study funded by the National Eye Institute that finished in 2001. Vitamin C, vitamin E, beta-carotene, and zinc have all been shown to reduce the incidence of macular degeneration and cataracts, making them excellent natural remedies.

By the age of 75, it is expected that up to half of all individuals will have cataracts of some kind. Anti-inflammatory and antioxidant-rich foods may help prevent and treat a variety of eye problems, including glaucoma, retinal nerve damage, loss of eye strength, and partial vision loss, in addition to macular degeneration and cataracts.

Diabetic retinopathy is another major issue that may be addressed with a good diet, and it’s now the primary cause of blindness in adults of working age.

Many eye vitamins help control blood sugar levels and hormonal reactions and absorb UV radiation and other wavelengths within the spectrum that harm our eyes, such as blue light emitted by modern gadgets like your phone, laptop, or tablet.

Antioxidants help protect healthy cells and prevent illnesses by decreasing inflammation and the quantity of blue light or UV radiation that may enter the eyes.

So, what are the greatest eye vitamins, and how do they affect eye health specifically? Let’s have a look.

The Top 7 Vitamins for Eyes

1. Lutein

Lutein, sometimes known as “the eye vitamin,” is an antioxidant that protects both the eyes and the skin. Leafy green vegetables, egg yolks, citrus fruits, and orange vegetables all contain this anti-inflammatory carotenoid phytonutrient. It travels throughout the body after being ingested, particularly to the macula and lens of the eyes.

According to Harvard University researchers, supplementation with six milligrams of lutein daily may reduce the risk of macular degeneration by 43 percent, indicating that “the eye vitamin” lives up to its moniker.

2. Zeaxanthin 

There are over 600 distinct varieties of carotenoids in nature, but only around 20 of them make it into the eyes. The most crucial are lutein and zeaxanthin, which are transported in the largest amounts into the sensitive macula of the eyes. Zeaxanthin, like lutein, helps preserve the eye’s tissue, lens, and macula, preventing glare, light sensitivity, and diseases like cataracts.

3. C vitamin

Vitamin C is an antioxidant that does more than simply combat colds; it also protects your eyesight by fighting free radicals and aiding your overall absorption of trace minerals and nutrients. Many Americans, according to studies, are weak in this important vitamin, which aids in the healing of injured tissue, reduces inflammatory reactions, prevents cellular mutations, and much more.

According to one long-term research, cataracts were also 60 percent less likely among 3,000 individuals (ages 43 to 86) who reported taking multivitamins with both vitamin E and vitamin C.

4. The antioxidant vitamin E

Vitamins E, A, and C act synergistically to protect cells and tissue against the consequences of inflammation. As a result, these fat-soluble antioxidants have been found to reduce the risk of age-related macular degeneration. In addition, combining vitamin E with vitamin A has been demonstrated to enhance healing and vision in those who have had laser eye surgery.

According to some studies, those who consume at least 400 international units of vitamin E daily, particularly when combined with vitamin A (as beta-carotene), vitamin C, and zinc, had a 25% decreased chance of developing advanced stages of macular degeneration. In addition, those with the greatest amounts of lutein and vitamin E had a much reduced relative risk of cataracts than those with lower intakes, according to a 2008 research including 35,000 people.

5. Zinc

When combined with other vitamins, zinc has been shown to preserve the retina and reduce the incidence of macular degeneration in studies. In addition, zinc is an essential vitamin for food absorption (involved in over 100 metabolic activities) and appropriate waste disposal, which helps prevent inflammation and cellular damage.

Zinc is beneficial to the tissues of the eyes because it is required for appropriate cell division and development, good circulation, hormone balance to avoid autoimmune responses, and regulation of inflammatory cytokines that assault tissue. However, because the human body can not produce zinc, we must receive it through foods such as fish, grass-fed beef, organ meats, and nuts.

6. Vitamin A

According to a study published in the Journal of the American Medical Association of Opthamaology, we need enough vitamin A to avoid xerophthalmia and night blindness, especially if we’re deficient in other nutrients.

Vitamin A is an antioxidant that has been demonstrated to help reduce eyesight loss due to degenerative diseases, including cataracts and macular degeneration. In addition, vitamin A, in combination with other antioxidants, seems to help delay the course of neuropathy (nerve damage) in the eyes, particularly diabetic neuropathy.

7. Omega-3 Fatty Acids

Omega-3 fatty acids provide a wide range of health advantages due to their anti-inflammatory properties and ability to slow down the consequences of aging. Unfortunately, people who eat many processed foods, hydrogenated vegetable oils, or a vegan or vegetarian diet that doesn’t contain seafood are more likely to be omega-3 deficient.

They’re so effective in protecting tissue that they’re often prescribed to persons with chronic tissue damage, such as arthritis and heart disease. Omega-3 fatty acids assist in maintaining blood sugar levels, which reduces inflammatory reactions, aids in the prevention of diabetes-related eye damage, improves circulation, and prevents cells from mutating.

The Healthiest Foods for Your Eyes

Do you want to know how to acquire the eye vitamins you need to keep your eyesight healthy as you grow older? Eat genuine meals first and foremost, and try to include some raw foods, such as uncooked vegetables. Cut and prepare your meals as near to the time you’ll be eating them as feasible to preserve antioxidants, and heat them at moderate temperatures as much as possible to prevent damaging sensitive phytonutrients.

Eat a lot of the items indicated below, either steamed, sautéed, or raw in the case of vegetables and fruit. In addition, to receive the maximum nutritional concentrations of eye vitamins and the least amount of pesticides or other dangerous substances, try to purchase organic, fresh, wild-caught foods as much as possible.

Some of the greatest foods to consume to receive the best eye vitamins are as follows:

  • Carrot juice with carrots
  • Vegetables with plenty of leaves (turnip greens, kale, mustard greens, collard greens, spinach)
  • Cruciferous veggies are cruciferous vegetables (broccoli, cauliflower, cabbage, Brussels sprouts)
  • Fruits of the citrus family (oranges, grapefruit, lemon, and limes)
  • Sweet potatoes
  • Beans (green)
  • A dozen eggs (including the yolk)
  • Berries
  • Papaya, mango, kiwi, melon, and guava
  • Corn
  • Red bell peppers
  • Peas
  • Seeds and nuts (sunflower, sesame, hazelnut, almond, brazil nuts, etc.)
  • Wild-caught fish, omega-3 meals, and foods rich in zinc are all good sources of zinc (salmon, mackerel, sardines, herring, halibut, tuna, etc.) In addition, grass-fed beef, cage-free eggs, and pasture-raised poultry are all available.

Eye Health Advantages

What role do vitamins and specific nutrients have in maintaining eye health? See the list below.

1. They protect against free radical damage (Oxidative Stress)

Free radical damage in the eyes is generated over time by things like a poor diet, blue light emissions from computer displays, and sun/UV light exposure. Certain vitamins and antioxidants, such as lutein and vitamin C, help battle free radical damage in the eyes. These vitamins are necessary to combat the effects of aging and slow down oxidative damage, which we all encounter as we age due to various circumstances (the ones listed above, in addition to alcohol or smoking and being exposed to various environmental pollutants).

Vision loss and illnesses such as macular degeneration and cataracts are all caused by oxidative damage, so the elderly and those who live unhealthy lives are more prone to vision loss and eye difficulties, particularly if they are deficient in specific vitamins. In addition, oxidative damage may impair blood flow to the eyes, damage blood vessels, complicate eye surgery and lead to conditions that impair vision, such as diabetes and heart disease.

2. Assist in the prevention of macular degeneration

Antioxidants such as lutein and zeathanin protect healthy cells in the eyes while also slowing the formation of cancerous cells that cause visual loss. Certain vitamins may help prevent age-related macular degeneration, which is the leading cause of blindness in the elderly.

According to estimates, more than 25 million people worldwide suffer from age-related macular degeneration or cataracts. The majority of those affected are people aged 55 and older living in industrialized Western countries. This is due to their diets being low in key nutrients but high in inflammatory foods.

Eye vitamins assist in filtering out a portion of the harmful short-wavelength UV radiation that harms the retina and other sensitive tissues of the eyes. The Age-Related Eye Disease Study found that a daily zinc consumption of 40–80 milligrams, along with the antioxidants beta-carotene, vitamin E, and vitamin C, delays the advancement of advanced macular degeneration by around 25% and visual acuity loss by 19% in those at high risk for these illnesses.

3. Reduce the Chances of Getting Cataracts

One of the most essential lens tasks in the eyes is to gather and concentrate light on the retina, allowing us to see clearly and without “cloudiness.” In addition, antioxidants are essential for keeping the lens clean and protected from harm; otherwise, cataracts may develop, blurring vision permanently.

Higher dietary intakes of lutein and zeaxanthin and the antioxidant vitamin E have been linked to a lower risk of cataract development and better eyesight in persons who already have cataracts in a research. According to the American Optometric Association, zinc insufficiency has also been linked to foggy vision and poor night vision since it helps transfer vitamin A from the liver into the retina.

4. Glaucoma, eye fatigue, glare, and light sensitivity are all reduced

The more the eye’s tissues are destroyed, the more distorted and sensitive vision becomes. The lens, cornea, retina, and macula all benefit from eye vitamins, which help keep your eyesight clear. They’re particularly critical for precise eyesight because they protect against cataracts, which obscure the lens and make it difficult to concentrate light.

Glaucoma, often known as tunnel vision or vision loss, is caused by damage to the optic nerves in the eyes, according to the Glaucoma Research Foundation. A nutritious diet rich in vitamins A, E, C, and zinc may help battle the disease.

5. Tissue Strengthening in the Eyes and Other Areas

As previously stated, oxidative stress and inflammation in the eyes cause tissue damage over time due to aging and an unhealthy lifestyle. Omega-3 fatty acids and antioxidants like vitamin E and C have been shown in studies to help people whose immune systems have been damaged by poor diets, persistent stress, and infections.

They’re also vital for newborns and children’s eye development. According to a review of numerous studies undertaken by Harvard School of Public Health researchers, babies who were administered omega-3 (DHA) enriched formulas had considerably superior visual acuity at 2 and 4 months of age than those who were not.

These eye vitamins assist in maintaining eyesight and have far-reaching advantages for tissues throughout the body (joints, cartilage, ligaments, and so on) by reducing inflammation, which is at the base of most disorders. So what good does it do you to have perfect eyesight if you can’t move around, balance, or function normally?


Do you know how many fruits and vegetables you’ll need to receive enough of these eye-healthy vitamins?

There is no standard guideline for daily antioxidant consumption of lutein or zeaxanthin at this time. In general, the more high-antioxidant foods you eat and the more diversified your diet is in terms of “eating a rainbow,” the better. However, there are a few principles to follow:

  • The majority of research demonstrates that consuming 10–30 mg of lutein per day or more has the best impact on eye health.
  • Aim for two milligrams or more of zeaxanthin each day.
  • Adult men and women should consume at least 75–90 milligrams of vitamin C per day, 1,000 milligrams (or 1,500 IU) of vitamin E per day, and 700–800 IU of vitamin A per day.
  • Adult women and men should consume eight to nine milligrams of zinc each day.
  • Men need 1.6 grams of omega-3 per day, while women need 1.1 grams per day, which may be achieved via a mix of supplements and meals.

In terms of your diet, what does this mean? First, eating a colorful, nutritious, and therapeutic diet rich in vegetables and fruits may readily attain these levels. One cup of kale, for example, has more than 22 milligrams of lutein and a significant amount of vitamin C.

While a well-balanced diet may provide adequate eye vitamins, supplements are indicated for persons who are particularly vulnerable to eye injury or who have difficulty absorbing nutrients normally, such as the elderly, who frequently have impaired digestive systems. For example, one Age-Related Eye Disease Study produced a supplement mix containing high amounts of most nutrients in the foods indicated for eye health.

Because several of these vitamins are “fat-soluble nutrients” that are best absorbed when consumed with a supply of lipids, it’s also suggested that you eat foods rich in eye vitamins and antioxidants together with healthy fats (fats). For example, combine these vitamins with omega-3 meals (salmon), coconut oil, olive oil, avocado, almonds, and seeds.

Last Thoughts

  • The eyes grow more vulnerable to injury as we age due to an unhealthy lifestyle and an overactive immune system, which causes the body to become overwhelmed with defense cells and hormones that destroy sections of the eyes. As a result, by the age of 75, close to half of all individuals have cataracts of some kind.
  • Lutein, zeaxanthin, vitamin C, vitamin E, zinc, vitamin A, and omega-3 are the most important eye vitamins. They aid in the prevention of free radical damage, macular degeneration, reducing glaucoma, eye tiredness, flare, and light sensitivity, and the strengthening of tissues in the eyes and elsewhere.
  • Carrots, leafy greens, cruciferous vegetables, citrus fruits, sweet potatoes, green beans, eggs, berries, papaya, mango, kiwi, melon, guava, maize, red bell peppers, peas, nuts, seeds, wild-caught seafood, grass-fed beef, and pasture-raised chicken are some of the greatest sources of eye vitamins.

Frequently Asked Questions

What foods are best for overall eye health?

A: It is difficult to say what foods are best or worst for someone based on their eye health. Many factors are involved, including the individual’s overall health and how often they eat certain kinds of food. For example, a vegan diet would be very unhealthy for someone with diabetes as it contains no carbohydrates that could potentially cause insulin spikes in the body.

What foods help repair your eyes?

A: Tea, watermelon, and dark chocolate are all good foods that can help you repair your eyesight.

Can eye vitamins improve vision?

A: The answer is no. Eye vitamins are formulated to help with macular degeneration, which often affects the central vision of an individual’s sight.
